The thyroid gland affects the function of nearly all systems within the body. Whether it is under functioning (hypothyroidism) or over functioning (hyperthyroidism) it can severely impact well-being. Immune function, weight control, sex drive, energy, temperature, skin and hair health, mental functioning, mood and many others all fall under the control of the thyroid gland.
Unfortunately the common blood tests for diagnosing thyroid conditions are not as accurate as modern medicine would like to believe. In cases of sub-clinical hypothyroidism, blood tests will not be able to detect the condition. Even a slightly under active or over active (sub-clinical) result can negatively impact proper health function.
Luckily there is a self test to check basic thyroid functioning. This is an easy and fairly accurate test to do at home. Before the use of the current blood tests this was considered to be the normal test, and many practitioners are reverting to this simple and cost effective method. The basal body temperature is a basic test of thyroid function. Body temperature reflects metabolic rate, which is largely determined by the hormones of the thyroid gland.
Performing the Test
To test basal metabolic rate:
Place the thermometer by the bedside before going to sleep. Make sure it ready to use.
Immediately on waking, place the thermometer under the armpit for a full 10 minutes. It is important to remain still. Read and record the temperature.
Do this for three or four consecutive mornings, preferably at the same time of day.
Menstruating women must perform the test on the second, third and fourth day of menstruation.
Interpreting the Test
Normal body temperature is 36.5 C + or - 0.2 C ( 97.6 F - 98.2 F).
Low basal body temperatures may reflect sub-clinical or fully developed hypothyroidism.
High body temperatures may point to hyperthyroidism.
Alcohol and diet can affect metabolism and therefore the readings so choose a time when a normal routine is being followed.
Treatment
If the results are considered to be minimal or sub-clinical, then thyroid function can often be helped with simple lifestyle changes. Daily exercise, diet and/or supplements are essential for a healthy functioning thyroid. Diet should include sources of iodine, folic acid, omega3 fatty acids, and selenium. If diet does not provide for this then supplements might be required.
If the findings are significant then discuss it with your health care professional.
